Coin slider



Dec. 5, 1961 F. c. PALLADINO COIN SLIDER Filed Feb. 11, 1960 IN VEN TOR. Fem/61344 AD/A/O United States Patent 3,011,614 COIN SLIDER Frank C. Palladino, Uniondale, N.Y., assdgnor to Precision Coin Devices, Inc., Stewart Manor, N.Y., a corporation of New York Filed Feb, 11, 196i), Ser. No. 3,110 11 Claims. (Cl. 194-55) The present invention relates to coin sliders, of the type particularly adapted for use with coin-controlled apparatus such as automatic washers and dryers, vending machines, and the like.

In coin sliders of the character described there is generally provided a reciprocable slider bar or plate which operates to control a mechanism, such as a switch of a timer in a connected electric circuit or an article for releasing mechanism, at one end of its stroke. The movement of such slider plate into operating position is normally inhibited, and the inhibiting means is inactivated by a coin carried on the slider and moved thereby.

As heretofore made, such coin slider devices as described above, in order to avoid inadvertent displacement of a coin disposed thereon, were formed and arranged and mounted with the slider plate reciprocating in a horizontal plane, with a coin or coins flatly disposed thereon and likewise in a horizontal plane, to minimize the chances of its rolling 0E therefrom. Such mounting and arrangement of the coin slider presented certain disadvantages. It necessitated that the coin slider project a substantial distance from the apparatus on which it was mounted. This required larger space for the installation of the apparatus mounting the coin slider. t also presented risk of injury to the body and apparel of persons moving about in the vicinity of such apparatus. Further, it presented a substantial purchase to persons desiring to tamper with the coin box which is generally associated with such a coin slider.

It is an object of the present invention to provide coin sliders of the character and for the purposes describe which may be mounted for the reciprocation of its slider bar or plate in a vertical plane, yet with a minimum of risk for rolling off, of any coin therefrom, to thereby eliminate undue projection of the device from the supporting surface and obviating the disadvantages flowing from such projection, as described above.

It is another object of the present invention to provide coin sliders of the character described which are capable of ornamental treatment, to thereby enhance the appearance of the apparatus with which it is associated.

It is still another object of the present invention to provide coin sliders of the character described which are of relatively simple and sturdy construction and which are proof not only against tampering but also against damage and distortion due to the efforts on the part of users to overcome any temporary inoperativeness of the device.

In coin sliders of the type of which the present invention relates, means are generally provided, for inhibiting the movement of the slide plate, which are released by the coin or token inserted into the device. One such means operable by the coin is responsive to the diameter thereof being moved into releasing position by the edge of the coin or token. The present invention is also directed to the provision of coinreleased slide-plate-engaging means of simplified construction and have simplified means for adjusting the same to be responsive to coins or tokens of different diameters.

The foregoing and other objects and advantages of the coin slider of the present invention will become more readily apparent to those skilled in the art from the embodiment thereof shown in the accompanying drawings, and from the description following. It is to be understood, however, that such embodiment is shown by way of illustration only, to make the principles and practice of the invention more readily comprehensible and Without any intent of limiting the invention to the specific details therein shown.

In the drawings:

FIG. 1 is a plan view of one embodiment of a coin slider of the present invention, adapted for operation by two coins;

FIG. 2 is an edge view of the same; and

FIG. 3 is a rear elevation of the same, with the coin chute removed, and other parts partly broken away, to illustrate details of construction and arrangement.

Referring now in greater detail to the accompanying drawings, the coin slider therein illustrated comprises a face plate, generally designated as 10, which may be formed of cast metal, of generally rectangular shape. The plate 16 is formed with an inwardly and then outwardly oifset flange 12, defining a recess on the inner side thereof. The flange 12 may serve to secure the face plate 10 in position and its inner longitudinal edge portions are parallel, to define guideways 14, for a slide bar or plate, generally designated as 16. The inner face of the flange 12 may serve to support upper and lower retainer plates, 18 and 29, respectively, inwardly of which the slide plate 16 is disposed, its edges resting in guideways 14. The face plate 1% is formed with a preferably rectangularly-shaped opening 22, whose dimensions will hereafter be made clear, and with a longitudinally-extending slot 24, running just short of the height thereof, between the opening 22 and its bottom.

The slide plate 16 is formed with bevelled upper corners 26, and with recesses 28, in each side edge at the end of bevels 26, whose top and bottom edges 3%, are inwardly tapered. The plate "i6 is also provided with a coin-receiving circularly-shaped opening 32, adjacent each recess 28 and opening thereinto; such coin openings 32 being so arranged that a coin disposed therein will project substantially into the adjacent recess 28. The opening 22 of the face plate 1% is of such size and the coinreceiving openings 32 are so disposed that the recess 28 into which each coin opening 32 extends underlies a side edge portion of the face plate opening 22, so that a coin inserted into a coin opening 32 will have a portion thereof underlie the side edge portion 54, of the opening 22, to be thereby retained in place, even in vertical position, between such edge portion 34 and the upper retainer plate 18 which backs up the slide plate 16.

The slide plate 16 is provided on its outwardly-facing side with a normally disposed arm 35, that projects outwardly through the slot 24 normally at its upper end, and carries an operating handle or piece 38, by which the slide plate '16 may be reciprocated in and out of operating position.

The slide plate 16 is formed with an upstanding rib as, which is adapted to be guided during reciprocation of slide 16 in a guide slot 4-2, formed in the retainer plate 18 and opening into the lower edge thereof, and a guide slot 44, formed in the retainer plate 29, opening into the upper edge thereof. The rib 4% has secured to its upper end an car 46, on which is anchored one end of a contracting coil spring 48, whose other end is anchored on a struckout lug 5%, formed in the upper edge of the upper retainer plate 18; such spring normally maintaining the slide plate 16 in its uppermost position in the recess of the face plate 10. Pivotally supported at the lower end of the retainer plate 18 are a pair of pawls 54, each opposite one of the coin openings 32, which are each tensioned by a spring 56, to have its hooked end 57, extend through an opening 58, formed in the retainer plate 18, to engage within the corresponding coin opening 32, in the event the latter is pushed down by the handle 38. Such hooked end 57, by engaging the upper edge of the coin opening biasing the offset hooked end 71 32, prevents and limits the downward movement of the slide plate 16 when there are no coins within its openings 32; the presence of a coin within each of the openings 32 disengaging the associated hooks 57 out of the openings 32 to permit the movement of the slide plate to its fullest downward stroke.

Th coin slider of the invention is provided with additional coin-released escapement means for limiting the downward movement of slide plate 16 in the absence of coins in either of the coin openings 32. Such escapement means comprises an approximately rectangular-shaped recess zhformed preferably in each longitudinal edge of the slide plate 16, below the tapered edge recess 23 and a pawl 62, pivoted on one end, on a pivot pin 64, which extends through a transversely elongated slot 65, formed in the flange 12. The pivot pin 64 is connected to a screw 68, which is engaged in a tapped opening 76, extending between the slot 66 and the outer face of the flange 12, whereby the pivot 64 of the pawl 62 is fixedly adjustable in the slot 66 by the turning of the screw 68.

The pawl 62 is pivoted in dependent position and is formed with an inwardly-extending offset end or hook 71, that is disposed in a groove 72, formed to accommodate the same in the flange 12 The pawl 62 is pro vided, intermediate its ends in greater proximity to its pivot 6 and adjacent the edge thereof facing the slide plate 16, with an inwardly-extending pin on which is mounted a roller 74, that is accommodated in a second transverse groove 75, formed in the flange 12 of the face plate 10. Tensioning means are provided for normally of the pawl 62, toward the inner recess of the face plate 1% This may comprise a torsion spring 78, mounted on a pin 8%, set into the flange 12 in a recess 82, formed therein, one end of which spring engages the side wall of the recess and the other end the hooked end 71 of the pawl 62.

In operation, when the slide plate 16 is held in inoperative position by the spring 4-8, the roller 74 carried by the pawl 62 engages against a portion of the adjacent edge of the slide plate 16 intermediate the upper recess 28, and the lower recess 69; being resiliently pressed thereagainst by the torsion spring 78. When the slide plate 15 is moved downwardly, without any coin in the coin-receiving opening 32, the roller 7 will move into the recess 23 and thereby cause the hooked end of the pawl 62 to move into the lower recess 66, under pressure of the torsion spring 78, to engage against the upper edge of such recess, to inhibit the downward movement of the slideplate 16. Such pawl 62 and recess 60 are so arranged that the interengagement of the two will inhibit or stop the movement of the slide plate before it reaches a position to operate the associated mechanism which it is intended to control. However, when a coin is disposed in a coin opening 32, with part of it projecting into the recess 28, such coin will, as the slide plate '16 is moved downwardly, engage against the roller 7- of the pawl 62 to maintain the hooked end 71 thereof over the flange 12 of the face plate it to permit the slide plate 1'6 to complete its downward movement without interference by the pawl 62.

Means are provided in the coin slider of the present it vention for preventing the return of the coin-loaded slide plate 15 before completion of the operative stroke of the slide plate and before the discharge of the coins from the slide plate. Such means comprise a ratchet 84, formed in one edge of the slide plate 16, immediately below the recess 60 and the pawl 86, mounted on the flange 12 adjacent the ratcheted edge of the slide plate; The pawl 36 is spring-tensioned, as by spring 33, which engages its free end to extend transversely of the inner recess of the plate It} to lie in the path of the descending slide plate, so that the descending slide plate, as it engages the pawl 86, biases its end downwardly to engage in the ratchet teeth and prevent the upward movement of the slide plate 16 until all of the ratchet teeth have cleared the pawl. The last takes place at the end of the completed. downward stroke of the slide plate, when the pawl 83 straightens out under the pull of the spring 88, into the recess In the last position, the pawl 86 may be upwardly tilted by the lower edge of the recess 69 and maintained in such upwardly tilted position by the ratchet. 34,.as the slide is moved to initial'inoperative position by' chute defined by a plate 90, secured by offset edges over the retainer plate 2%, in a manner readily understood and shown in FIG. 2. Such discharge is facilitated by inwardly curved wire springs 92, that are mounted on the etainer plate it} in upwardly-extending position, over-- hanging the slide plate 16, and which, when the slide plate 16 reaches its'lowermost position, have their free ends enter slots 94, formed in the slide plate, to engage underneath the coin held in the slide plate and guide it outwardly therefrom over such pins and outwardly of the retainer plate 2d; between the latter and the chute plate 95?.

While the plate 90 forming the chute is shown in the drawing to be parallel to the face plate 10, it may here be stated that where the device of the present invention is in a horizontal position, such chute may be formed to slant downwardly and inwardly to facilitate the dropping of the released coins out of the device.

This completes the description of the coin slider for coin-controlled apparatus of the present invention. It will be readily apparent that such coin slider may be mount d compactly, in vertical position, and will effectively operate in such position. It will also be appareat that such coin slider is readily susceptible of decorative treatment. It will be likewise apparent that such coin s ider of the invention may be most easily and conveniently adjusted for use with coins or tokens of different sizes by means of turning an easily accessible screw.

it will also be apparent that numerous modifications and variations in the coin slider of the present invention may be made by anyone skilled in the art, in accordance with the principles of the invention hereinabove set forth, and without exercise of any inventive ingenuity.
